Buffalo Tools Electrical Supplies - Recent Questions, Troubleshooting & Support

try googling buffalo tools 7,000 w propane generator manual 7000 kw is a very large unit - 7,000,000 watts

The switch is probably generic.. go to a Lighting store and see if they have equivalent

have the voltage regulator system checked in the regulator the voltage controls the amperage allowed and it that unit is not working properly then there will be no current out put that regulator could be part of the control board for the main ac out put and may have developed a fault in the section for 12 volts on the board there is a limit on the charge rate for the battery and if it is exceed it may have damaged that circuit or possible blown a fuse in the amperage circuit

There have been several factories in china that have made the motors used on buffalo generators, a couple of these are Lifan and J.D. as in Jiangdong.All of these motors are very similar to honda motors.The 6.5,13,and 15 h.p. motors are real brutes and hold up very well.

Give us a call when you are with the Generator and we will run through it with you. Call your local office and speak to an engineer: http://www.generatorguru.com/ask-the-guru/ Generator Guru

if you cannot get the specs from on line or from a service agent , generally the following apply:- water cooled engines inlet hot .010"--exhaust hot .012" for air cooled engines inlet hot .012"-- exhaust hot .014"

Make sure the power switch under the clear rubber cover is on. Ifd it is, thenlook for a smoked electronic voltage regulator

HOPE THIS LINK WORKS. http://www.buffalotools.com/manuals/gen154manual.pdf it is the Gen you got, I have same.. Condenser failed after 7 yrs. Just suddenly stopped putting out. Kept running nicely though!

The breaker itself is worn and weak. Replace it.

Could be lost exciter current. This is how to restore it - Connect 16 or 18 gauge wires to a 12 volt battery. With generator running, insert bare ends of wires into AC outlet - one to Hot, the other to Neutral. Insert and remove quickly. There should be a flash and power will be restored. If not, repeat until you get that flash and output current restored. Using light gauge wires is so that if you are too slow to remove them once AC is restored. they will burn out before the battery suffers from the AC incoming. Be quick and be careful.

find out who manufactured the engine... if it's a honda knock off a honda recoil might work and you can get an after market one for cheap... like $30 USD or something close

Check the rotor rings for cleanliness, they should be shiny, check the brushes and the capacitor, located in the end of the alternator bell housing cover

Assuming the speed is correct check the voltage on the rotor brushes during running (Caution) It should be DC. If you have low or no DC voltage then the capacitor in the end of the generator housing is bad, or the AVR. If you do have voltage then make sure the slip rings are clean and shiny, from there you may have a rotor or stator issue that needs carefull resisitance check
